Document EventQueue closure semantics for AgentExecutor

[Copilot]

The issue asks when EventQueue is closed for AgentExecutor.execute(...), which affects how agent implementations should handle the queue lifecycle.

• Queue lifecycle guidance
  • Added Javadoc to AgentExecutor.execute(...) describing when the server closes the queue (final events, fire‑and‑forget non‑blocking closure) and why agents should not close it.

Example:

@Override
public void execute(RequestContext context, EventQueue eventQueue) throws JSONRPCError {
    // enqueue events via TaskUpdater; do not close eventQueue
}

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• repo.gradle.org
  • Triggering command: /usr/lib/jvm/temurin-17-jdk-amd64/bin/java /usr/lib/jvm/temurin-17-jdk-amd64/bin/java --enable-native-access=ALL-UNNAMED -classpath /usr/share/apache-maven-3.9.12/boot/plexus-classworlds-2.9.0.jar -Dclassworlds.conf=/usr/share/apache-maven-3.9.12/bin/m2.conf -Dmaven.home=/usr/share/apache-maven-3.9.12 -Dlibrary.jansi.path=/usr/share/apache-maven-3.9.12/lib/jansi-native -Dmaven.multiModuleProjectDirectory=/home/REDACTED/work/a2a-java/a2a-java org.codehaus.plexus.classworlds.launcher.Launcher -q -DskipTests=false test (dns block)
• repository.jboss.org
  • Triggering command: /usr/lib/jvm/temurin-17-jdk-amd64/bin/java /usr/lib/jvm/temurin-17-jdk-amd64/bin/java --enable-native-access=ALL-UNNAMED -classpath /usr/share/apache-maven-3.9.12/boot/plexus-classworlds-2.9.0.jar -Dclassworlds.conf=/usr/share/apache-maven-3.9.12/bin/m2.conf -Dmaven.home=/usr/share/apache-maven-3.9.12 -Dlibrary.jansi.path=/usr/share/apache-maven-3.9.12/lib/jansi-native -Dmaven.multiModuleProjectDirectory=/home/REDACTED/work/a2a-java/a2a-java org.codehaus.plexus.classworlds.launcher.Launcher -q -DskipTests=false test (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
